Actually I take it back, DR3 implements a new game+ system instead of a free roam, so I started again and all my stats carried across, except there seems to be bloody glitches with a few things. For starters I've collected every blueprint now but am still a few short, and no I haven't missed any, the game hasn't given me some in the 1st game, when it should have, a common glitch apparently.. Like doing a jigsaw and finding a piece missing at the end - infuriating to say the least.
And don't know if this is a glitch or not, but your zombie kill count carries over throughout games, but the pp trials which require you to kill x amount of zombies don't, you start a new game and you start from 0 again, seems weird as your completed pp trials carry over just fine. So if you kill 1000 zombies for a trial, but start a new game before beating the 10,000 zombie trial, your 1000 trial is passed ok, but you have to start from 0 again to hit the 10,000 one, considering there's a 100,004 one, I don't think I'll bother, Ive only just hit 53,000 over 2 full games worth!
Anyway, too glitchy for me to even bother thinking about 100%ing it.. Which means I'm pretty much done with it.
